Worried about 2.6.39.x kernel

August 13, 2011 — BarryK
Drake Puppy 0.3 has the kernel. It seems like a nice kernel, except for one thing...

A few times in Woof when I built a live-CD of Drake Puppy, I found that a file, and in one case a complete directory, were missing from the main SFS file, 'puppy_drake_0.3.sfs'. This is running on my new laptop, with Intel i3-core CPU.

I have no explanation for this, they just disappeared. They disappeared from sandbox3/rootfs-complete, the complete filesystem used to create the SFS, so it is not a problem with Squashfs. They should have been copied into rootfs-complete, somehow they never got there.

That is, the code-loop in '3builddistro' copies packages into sandbox3/rootfs-complete, and the files are in the packages, but don't appear in the destination. It is just a tight loop with the 'cp' command.

After this happened three times, I lost all confidence in the kernel, as I could not see any other reason for the disappearance. Since then I have been using Wary, with 2.6.32.x kernel, for all development work, and everything has been fine. Note, I am working in a partition with ext3 filesystem.

I am wondering if there is something in the configuration of the 2.6.39.x kernel -- cgroups maybe? -- that is causing this. I might try a recompile of the kernel with more conservative configuration.

"2.6.35 is good choice, Intel and some other companies maintain it because they used it for commercial products. But who knows, maybe one day they'll move on to a newer kernel, while 2.6.32.x will be maintained as long as RHEL 6.x is around. Plus, it had 44 bug-fix releases so far, which is very impressive.

"Barry, I have seen a similar problem in making sfs's. I "solved" it by including the option -noI in the command line to mksquashfs. I had repeated the problem several times and that option stopped it. That was with the kernel in Lucid. BTW, Three-Headed Dog is a new Puppy Derivative built with the kernel that 01micko built for Slack Pup.
